CLEANSING-TRUNK FOR COTTON OR OTHER PICKERS.

SPECIFICATION forming para of Letters Patent No. 690,653, dated January 7, 1902.

I Application filed August 30, 1901. Serial No. 73,80i. (No model.)

To @ZZ whom it may concer-71,:

Be it known that LFREDERICK H. L. J AMES, a citizen of the United States, and a resident of Pawtucket, in the county of Providence I and State of Rhode Island, have invented. a

new and useful Improvement in Cleansing- Trunks for Cotton or other Pickers, (Case 0,) of which the following is a full, clear, and exact description, reference being had to the ac- Io companying drawings, forming a part of this specication, in explaining its nature.

The invention relatesto a cleansing-trunk for cotton or other pickers which has a passage through which the cotton or other ber t5 is drawn or impelled, a passage adapted to receive dirt from said cotton or other ber of peculiar location and form through which the dirt is drawn by an exhaust, `and intermediate dirt-receiving chambers adapted to re- 2o ceive dirt from thepassing cotton or ber and to hold it and provided with movable bottoms hinged at the lower outer corners of the trunk, extending inward from said cor,- ners to form the bottoms of the chambers and n.5 movable downward upon vertical arcs when desired to permit the contents of the chambers to be delivered to the dirt-escape passage.

I will now describe the invention in con# junction with the drawings, wherein- -a cleansing-trunk having the features of my invention; and Fig. 2 is a view in horizontal cross-section upon the dotted line 2 2 of Fig. 1.

Referring to the drawings, A is a passage in which the cotton or other ber is fed.

B is a gridof bars forming narrow openof these bottoms comprises a thin atleaf ofd suitable material of sufcient area to fully inclose the bottom of the chamber and bear slightly against the under surfaces of its Figure l is a view, partly in side elevation 1 and partly in horizontal vertical section, of`

walls. Each is pivoted at the lower corner of the trunk, the bottoms D at d and the bottoms D at CZ. Preferably the pivot acts as a connecting-rod, in that the hinges d2 of each bottom are made fast to a longitudinal pivot rod or shaft, the rod or shaft connecting a number of bottoms and providing means whereby they may be simultaneously moved. The pivot rodor shaft has bearings in the hangers d3 d4, respectively, which are bolted or otherwise attached to the sides of the trunk and which have their ends turned inward upon the top of the trunk to rest thereon. The bottoms are held in closed position by overbalancing-weights-the line of bottoms D by one or more ov'erbalancing-weights E and the line of bottoms D by one or more overbalancing-weights E. The weight E is represented as suspended by the rod e to an arm e', extending outward from the shaft d, the connection between the rod e and the arm e being such as to permit the swinging of the rod on the arm. The weight E' is similarly attached to the arm e2, extending from the shaft d'. Each bottom, it will be seen, swings upon its holding-shaft as a center and from about the center of the truuk downward and outward toward the sides, so that when wide open they extend from the lower corners of the trunk downward and inward. They are inclosed by the xed bottom F, which isinclined from the lower corners of the trunk downward and inward, the inclined sections being connected by a rounded portion f. Within this rounded portion is the wasteescape passage G and into which the inner `ends of the movable Vbottoms may swing. The passage is provided with a suitable airexhaust (not shown) and opens into the escape-pipe g. In Fig. 2 the bottoms are shown closed, and the line of movement of their inner ends is indicated by dotted lines.

is closed by their/'bottoms D D', so that no (cross-draft or currents of air may pass between the cotton or ber passage and the dirt- Any portion of the dirt-receivingichambers CC passage. As often as may be necessary the bottoms may be tipped upon one side of thel trunk orrthe other, or both, and the contcnts of the chambers which have been deposited upon the upper surfaces of the bottoms are dislodged from them and delivered into the dirt-escape passage, through which it is drawn or impelled by the exhaust, the bottoms swinging from their inner ends downward into the escape-passage and forming inclined planes opening into it and upon which the dirt slides from them, the inner ends of the bottoms being elevated above the bottom of the escape-passage, so that room is provided for the escape of all the dirt from the bottoms when in their wide-open position. They preferably are opened in groups by lifting the overbalancing-weight, its suspending-rod, or the arms to which it is attached. They may be jarred by being brought into contact with the bottom F, and upon the release of the overbalancing-weight they will automatically resume a position to close the chambers. The bottom F not only provides room for the escape-passage G, but also a chamber H between the escape-passage and the chambers C C', in which the bottoms may swing back and forth from the chambers to the exhaust-passage.

While I have represented each of the dirtreceiving chambers as having an independent hinge or movable bottom, I would say that a bottom may be employed common to two or more chambers. I would also add that I do not limit myselt` to the means described for holding the bottoms closed or for moving them from outside the trunk.

It will be seen that the bottoms when open are inclined inwardly from the sides of the trunk and serve as slides upon which the dirt is directed from the dirt-receiving chambers to the dirt-escape passage.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United Statesl. In a cleansing-trunk for cotton or other pickers, a passage through which cotton or other fiber is adapted to be fed, a grid comprising the bottom of said passage, a dirt-receiving chamber and dirt-escape passage beneath said grid, and a bottom to said dirt-receiving chamber movable from a closed position, when it separates said chamber from the dirt-escape passage, to an open position providing an inclined egress from said dirtreceiving chamber into said dirt-escape passage.

2. In a cleansing-trunk for cotton or other pickers having a passage through which cotton or other ber is adapted to be fed, a bottom having openings through which dirt from said passing cotton or liber may escape, dirtreceiving chambers beneath said bottom in parallel lines separated from each other by a longitudinal partition, and bottoms for said lines of chambers, one set of which are hinged at or near the lower corner of the trunk at one side and the other set of which are hinged at or near the lower corner of the trunk at the other side and which bottoms are movable upon said hinges or pivots from a closed position to an inclined position, and an escape-passage common to both chambers and bottoms.

3. In a cleansing-trunk for cotton or other pickers, a passage through which cotton or other fiber is fed, a grid comprising the bottom of said passage, an escape-passage for the dirt and intermediate dirt receiving chambers in two longitudinal lines continuously connected with the. said iirst-named passage and intermittently connectible with the dirt-escape passage.

4. In a cleansing-trunk for cotton or other pickers, a passage through which cotton or other ber is adapted to be fed, a grid comprising the bottom of said passage, an escapepassage for the dirt, dirt-receiving chambers intermediate the two passages constantly connected with the passage through which the cotton or fiber is fed, to receive the dirt therefrom, a chamber between said dirt-receiving chambers and the dirt-escape passage having inclined walls extending into said passage, and bottoms for said dirt-receiving chambers movable from a position which closes said chamberslto a downward-inclined position par` allel with the inclined sides of said intermediate chamber and whereby the dirt-receiving chambers are connected through said intermediate chamber with the dirt-escape passage and the inclined bottoms serve to direct the dirt into said escape-passage.

5. A cleansing-trunk for cotton or other pickers having a passage through which cotton or other ber is fed, a grid comprising the bottom of said passage,an escape-passage and a series ot' dirt-receiving chambers connected with the said Erst-named passage, each having a hinged bottom and an overbalancingweight for holding it in a closed position.

6. In a cleansing-trunk for cotton or other pickers, a passage through which cotton or other fiber is fed, a grid comprising the bottom of said passage, a dirt-escape passage, a plurality of dirt receiving chambers constantly connected with the ber-passage, and a movable bottom for each chamber hinged at or near the outer side of the trunk, the said bottoms being so connected with each other that a group of them may be simultaneously tipped from a closed position to a po sition providing an inclined egress into the said escape-passage.

7. The combination in a cleansing-trunk for cotton or other pickers of a passage through which cotton or other ber is fed, a grid comprising the bottom of said passage, dirt-receiving chambers beneath it and connected therewith, a dirt-escape passage and a movable bottom for said dirt-receiving chambers at one side of the trunk, adapted to be movable from a closed position to a position inclined with respect to said side, and a pendent overbalancing weight connected with said bottom.
